Objective: To decompose the SQ complex prescription which was composed of Radix notoginseng and Radix rubiae. Methods:An animal model of Cu-IUD-wearing rabbits was established and was given SQ complex prescription, Radix notoginseng or Radix rubiae alone. Hemorheology markers, endometrium microvessel count, 6-K-PGF1α, TXB2, and t-PA were studied. Results:SQ complex prescription, Radix notoginseng and Radix rubiae all could reduce the endometrium microvessel count, degrade the erythrocrit, the blood viscosity at low, medium and high shear ra...
